Our sewage damage restoration process is designed for complete repair — thorough damage assessment, professional restoration of affected materials, and full reconstruction when needed to bring your property back to pre-damage condition.
We begin with a comprehensive assessment of all sewage damage — inspecting floors, walls, subfloors, and structural elements to identify the full scope of restoration work required.
Using professional moisture detection equipment, we identify hidden moisture in walls and floors. Complete drying is essential before restoration begins to prevent mold growth and future problems.
Containment and contamination control procedures designed to help isolate affected areas, reduce hazardous sewage spread, and support safe sewage damage restoration and reconstruction.
Sewage-damaged materials that cannot be restored — such as saturated drywall, carpet, or insulation — are carefully removed and disposed of to prepare for reconstruction.
Our team repairs and rebuilds damaged areas including drywall, flooring, baseboards, and structural elements — restoring your property to safe, pre-damage condition.
Once sewage damage restoration is complete, we conduct a final inspection to ensure all repairs meet quality standards and your property is fully restored and safe for occupancy.
A structured sewage damage restoration process ensures complete repair, prevents future problems, and fully restores your property to safe, pre-damage condition.

Sewage cleanup is only the first step. Even after sewage is removed, hidden damage remains in floors, walls, and structural materials. Without proper sewage damage restoration, moisture trapped inside materials leads to mold growth, structural weakness, and ongoing health risks — problems that get worse and more expensive over time.
Professional sewage damage restoration addresses hidden damage, prevents long-term problems, and fully restores your property to safe, pre-damage condition.

Nijen's team replaced and build a privacy wall on our back deck last Friday. They were professional, and efficient and we couldn't be happier with the end result. Thank you to Nijen and his team. We would definitely hire them again for our renovation needs and recommend them to everyone. TianaPosted on Mathew WhiteTrustindex verifies that the original source of the review is Google. I engaged First On Site as a preferred vendor through my insurance provider following an unsatisfactory experience with another restoration company. Understandably, I approached the process with some hesitation. From the outset, the team at First On Site demonstrated exceptional professionalism. They maintained clear and consistent communication, keeping me informed of all timelines and progress updates. Their responsiveness and attention to detail far exceeded my expectations. Upon arrival, the crew began work immediately and remained focused and diligent throughout the day. Their efficiency, professionalism, and respect for my property were commendable. Additionally, the team effectively liaised with my insurance company, ensuring the scope of work was completed exactly as described and to a high standard. I would not hesitate to recommend First On Site to anyone requiring disaster management or restoration services. Their commitment to quality and client satisfaction is truly exemplary.Posted on siddharth khannaTrustindex verifies that the original source of the review is Google. I called them at 7 am for an emergency basement pipe burst leakage and they sent out a crew within a couple of hours who knew exactly what needed to be done. They documented the damage thoroughly for insurance purposes and I faced no trouble. The team at GTA are professional and helpful. Totally recommend!Posted on Mark EsdaleTrustindex verifies that the original source of the review is Google. After a ice storm related basement flood the GTA team showed us what service meant!. They were here very quickly, with the proper drying equipment and some great staff members. They removed old carpeting/under padding and the bottom 12 inches of drywall from the affected flood area, installed and left drying machines, were back in a week to repair the drywall. We could not have asked for a better job, very glad we chose them.
